[BUG] `docker compose restart` doesn't execute `post_start` hook

[fpotier]

Description

When a service is restarted using the restart subcommand the post_start hook is not run but using sequentially stop then start executes the hook as expected

Steps To Reproduce

With this compose file:

services:
  bash:
    image: bash
    command: bash -c "while true; do echo 'Running...'; sleep 60; done"
    post_start:
      - command: bash -c "echo started >> /logs"

Run the following commands

$ docker compose up -d

Anything else?

I didn't give it a try but pre_stop hooks might also be skipped
